Application led July 23, 1909. Serial No. 509,077.

To all whom it. may concern:

Be it known that I, FELIX A. WASCHKA, a-l citizen of the United States, residing at Crowley, in the. parish off Acadia and State of Louisiana, have invented a new and useful Lubricator for Furrow-Cutters, of which the following is a specification.

The invention relates to a lubricatorv for furrow cutters for plows.

The object of the present invention is to provide a simple, inexpensive and eicient lubricator for furrow cutters, adapted to feed a lubricant to the hubs of a plurality 'of disks, and equipped with means for controlling the flow of the lubricant and for also cleaning the oil passages leading to the hubs to prevent the same from becoming clogged. Y

With these and other objects' in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that Ivar?y rious changes in the form, proportion, size and minor details of construction, within .the scope of the claims, may be resorted to without departing from the spirit or sacrificing' any of the advantages of the invention.

In the drawings: Figure 1 is a rear elevation of a furrow cutter provided with a lubricator, constructed in accordance `with this invention. Fig. 2 is a side elevationof the same. Fig.' 3 is a transverse sectional view,` illustrating 1 the manner of mounting the disks. Fig. 4 is 'a detail sectional view,

taken `substantially on theline 4 4 of Fig.'

3. Fig. 5 .is a detail .sectionalfvvievw illusj trating the construction ofthe latch 'of the oil regulating and hole cleaning. device.

Like numerals of reference'"designate correspondinggparts inwall the'figures of the drawing.v i

The device comprises in -itsl ,construction a plurality` of straight flatdisks 1 of any preferred number, designed to be located in frontof the plowshare (not shown) and adapted to cut the soil into a plurality of. strips, as the soil is turned over by the mold board of the plow to form a furrow. By cutting the ground as it is plowed it o bviates the necessity of using a vdisk harrow after plowing, and itena'bles the plow to run easier. The disks are provided with cylinv `drical hubs 2, having annular attaching anges 3 to which the disks are' riveted .or i

otherwise secured. In the embodiment of.v

the invention illustrated inthe accompany! ing drawing, two furrow cutting'disks are illustrated, butthe number may be varied. Each is preferably equippedwith a vrroller ,bearing consisting of an annular series of rollers 4, arranged in spaced relation and maintained in such relatlve arrangement by longitudinal rods 5, interposed between the rollers and connecting endv ringsv 6, which confine the rollers in the hub 2 of the `disk 1. Any other preferred form of bearing, however, mayl be employed. The roller bearings are arranged on a tubular axle 7, forming a lubricant chamber and also supporting an intermediate collar 8 and end collars 9,- secured to the axle by set screws 10 and .11. The intermediate collar or sleeve8 has a central portion of a diameter to fit snugly on the axle, and itis also provided with en.

larged annular end portions 12, forming terminal bearing cups and receiving the inner ends of the hubs 2 of the disks. collarxgsv 9 are provided with inner annular enlargements 13, forming cylindrical cups-f and receiving the outer ends ofthe hubs of. the disks. The set screws 11 pierce the collars 9 and rigidly and adjustably secure the same to the end portions of the axle.

The axle is tubular and is provided The outer Y .within the hubs 2 of the disks 1 with oil holes 14, adapted to permit vthe passage ofa lubricant tothe bearings. Theinner end l capable also of movement through the saine j to clean theoil holes;v The rod or mernbe '21 is arranged at an inclination ,whenjzf holes are open, and the lugsor-projecti which are of different lengths, are tap'ere 'and their lnnerzor upper portions are'of a1 diameter to positively close 'the foilf'holes, while their `lower or outer portions are sufoiently small to pass vthrough and clean they holes.l The outer portion of the hole c1eani1igandl lubricant .regulating rod or member extends through a slot V25 Iof a cylindrlcal cap 26, threaded on. the outer end v of the axle and provided'vvith an buter end Wall in Which the slot 25 is formed. One of the Walls ofthe slot 25 is provided with teeth 27, and the rod or member 21 is provlded with a spring actuated latch 28, adapti l' ed to engage with the teeth for securing the rod or member 21 in its adjustment. The latch consists of a lever pivoted at its inner end 29 and engaged at an intermediate point by aspring 30, secured' to the adj acent edge of the rod or member, and adapted to force the latch outwardly with respect tov the rod or member, as clearly illustrated in Fig. 5

. of the drawing. Theouter portion ofthe j against the rod by the operator. v 20 latch extends b'eyondl the cap 26, and is adapted to be `readily pressed. inward The rod is movable vertically and by oscillating it, itv isadapted to clean they oil holes, admit a quantity of lubricant to'the bearings andl l. Aclose the oil holes to cut oifthe flow of the lubricant. The lower end 'Wall of the vertical slot'of the cap is located a suicientdisy j ltance above the bottom of the latter to form arrec'eptacle for a considerable quantityof vv'Havingfthus fullyr described my invention what Ij'claim as new'and desire tol-secure by Letters'Patent, is I 1, yAdevic'e ofthe class'described'includ-f ying-a plurality lof rotary elements having hubs, a tubular i axle receivingqthe' rotary elements and forming a lubricant. chamber andprovidedA Withspaced oilvholes, and av longitudinally` arranged combined cleaning and regulating member movablv mounted l'Within the axle 'andl 'provided `1th correspondingly lspaced taperedf'fprojections lo'-v ,cated at [the said oil holes andgarranged to hubs, a tubulfar axle receiving the; rotary elements and vforming a lubricant chamber'and provided with oil holes located'With-inthev hubs, a combined cleaning and regulating member pivotally mounted Within the axle and provided With projections forming closures for the oil holes and adapted also to clean the same, and means for securing the member in its adjustment.'

3. A device of the class described including a plurality of rotary elements having hubs, a tubular axle receiving the rotary elements and forming a lubricant chamber and provided with oil -holes located Within the hubs, a combined cleaning and regulating member-pivotally mounted Within the axle and provided With projections forming closures for the oil holes and adapted also to clean the same, and means for securing the member in its adjustment including a spring actuated latch arranged to lock and release the said member.

4. Aidevice ofthe class described including a tubular axle forming a lubricant chamber and "having an outlet for the lubricant and provided with 'a vertical series of teeth,

a'rotary element mounted on the axle at the outlet, a cleaning and regulating member mounted Within the axle and having `a projection forming a closurefor the outlet and adapted also yto `clean the same, and a latch `carried by the; .member 'and arranged to engage the teeth for securingthe member in )its adjustment. v

' 5. vA device ofl the Vclassdescribed including va tubular axle forming a lubricant chamber and having an outlet, a rotary element .provided 'with a hub located at the said outvlet, a; rod mounted within `the axle andi having a closure forth'eoutlet adapted also to Iclean thesajme, -aflcap lfitted on the axle and providedfwith. af slot receiving the outer portion of the member, alocking device mounted on the member and .engaging with the cap for securing the 'former in itsadjustment.
